I’m no agricultural economist,

and this is way off topic, but this sort of thing really boils my blood. The genetic engineering, fertilizers, and chemical pesticides of the green revolution tripled yields and increased food consumption and life expectancy among the world’s poor by decades. Some of us are rich enough to start worrying about the pollution – as rich people should. But this woman is pushing organic farming for India? You don’t think shit is polluting too? Where are you going to get the land? She’s an elitist crank. Meanwhile here’s the NYT obituary of Norman Borlaug. And here’s data from irri.org on Indian rice yields, per hectare. You can see the green revolution regression discontinuity in the raw data.
